SPECIFICATION forming part of Letters xatent No. 713,054, dated. November '11,

Application filed April 2, 1902.

To @ZZ whom it ilmy-couccr'tf l Be it known that I, EDWARD?. BURN-IAM, a citizen of theUnit'ed States, residing at Albany, 'New York, have invented certain new and useful Improvements in D umping-Ww gon Boxes; and I do herebydeclare the following tobe a full, clear, and exactdescription of the invention, such as will enable others skilled IOl i ism; Fig. 8, a longitudinal sectional view yof r y act of being closed.

The numeral 1 shows the side-board of myby the metallic strips 3, the lower ends of f ing-slightly underthe wings 2,. which.fortn 5" in the art to'which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference'marked thereon, which form a part of this specification.

The object of my invention is to providea new and improved dumping-wagon box for use on any of the. ordinary forms vof workwagons in common use.l

. In the drawlngs, Figure 1f is a side eleva' tion of my box;

Fig. 2,'a bottom plan view; Fig. 3, a vertical sectional view taken on line a a of Fig. 2; Fig. 4, a cross-section ofthe rod by means of which the'bottom is oper` ated, showing in end elevation one of the lifting wings or levers; Fig. 5,a plan view of one of the operating-levers; Fig-6, a side eleview of the operating-lever and its mechanmy box; Fig. 9, a side elevation of one end of one of the truss-rods; and Fig. an end elevation of the wings/'forming the bottom of the' box, showing' the left-hand wing in the Wagon-box which is stiffened or strengthened said'strips 3 passing under the lower vedge of the side-board `1 and forming not only supports to vthe revoluble rod 4, but also journal-boxes,in which said rod 4 is held and allowed toy rotate. The revoluble rod 4 is preferably set under the lower edge of the side-board 1 and is preferably let into a groove therein sufficientlyshallow so as not to receive the Whole rod, but to allow the rod to present-about two-thirds of its surface below the groove, as seen iii-Fig. -1. On this rod 4 are fixed; catches '5, these catches projectthe boxbottom,`the vpreferred form of these catches-being shown in Fig. 6, wherein it is shown that the inner surface of the outer Serial No. 101,091. No model-l hooked end forms a portion of thefarc of thecycle of action of the catch as it revolves with the rod-4 1'. e., if a pair of Compasses be used, one leg resting inthe center ofthe rod 4 and the' other set at the upper inside cornerof the hooked end and swung downward, it will be seen that the inner surface of Athe hooked end is a portion of the circle so striick." This is so designed that when the 'catch'5 is in its normal retaining position the interlocking end of the latch 7 will have the least possible tendency to press the catch 5 downward. On-

vthe wing-pieces of the bottom are attached the latches 7, practically as seen in Fig. 2, arranged to lock with the catches 5, practically as shown, when the bottom wings 2 2 are' closed.

Centrally alongthebott'om 2 runs the revovluble rod (i, journaled -to stay-piecesattached to the box. On this rodv G are hinges S, one set being attached to one vofthe wings and the v.other set to the remaining wing and arranged so the wings may be opened and closed separately. Also on this rod G are set 'winged pieces 9, the function of' which Vis to assist in forcing'the wings upward and to close when the rod G is operated for that purpose.

At the under and forward end of my box and affixed. to the rod 4 are plates or rings 10, to which are ,pivot'ed lever-'s 1 1 and 1 2,- the inner ends of which levers are pivot-ed to disks 16 and 17 said disks being affixed to the revoluble rod 6. On the rod (i is lixed the adjustable throwing-lever 14, resting, preferably, between the disks 1G and 17. The clutch-le ver 15, forming a part of the lever 14, has an up and -down motion when its handle is pressed and released, and as it operates the' same as all such levers which are in common and every-dayuse its mechanism is not more particularly set forth, as it is well known to those skilled in the art. At thelower end of gthe piece 15 is a notch 20, and when its lower end yis in its normal position'it catches the pin 18 on disk 1,6, and When'lever14 is thrown -to one side it revolves disk 1G and rod 6, operating one of vthe wings 2of the box-bottom; but when 15 is clutchedl the notch 20 regis ters vwith the pin 18, and the-lower end o1? then catches pin '19'and operates one of the ,wings 2 ofthe wagon-box. Eachof the levers 12'ha'sav slot-13 at the end attached to IOO 2, leaving a V-shaped indenture between their inner edges, and over this V-shaped -indenture is set the inverted-V-shaped piece 24, so as to prevent dirt or sand fromlling the indenture, and the: inverted/#V shaped piece24 is fastened, preferably, to the ends' of the box and is also preferably stayed by upright posts 22, the lower ends resting on the rod 6, as seen in Fig. S.

"In order thatthe rod (S shall not spring or Vsag, I make use of the truss-rod 28 and its central support 2l, its outer ends passing through a cross-piece 25 and having a tight-.-

ening-nut at its free ends, as seen in F-ig. 9.

Thus trussed the rod 6 is able to withstand' all downward .pressure without sag-ging or lget-'ting out. of true, and anyslackening coming from long use may be taken up by the nuts at the free ends of the'rod 23.

, lVhen my box is arranged as. seen in Fig. 8, it is ready for carrying sand,gravel, or any other similar matter;.vbut when I desire to draw lumber or-like long material I remove the end-board at the rear of the box. This end -board is preferably made of the two boards 26 and 27, and they are set in grooves preferably made in the side-boards, or cleats may beaiiixed tothe side-boards forming such grooves, as may be' desired. The end-boards 2G and 27 then may be removed andreplaced at pleasure and any long materials, such as lumber, be readily placed in the boX. The object in having two boards for an end-board is that board 26, with the stay-rods'28, helpsy to stilcn the side-boards, while board 27 being set at an angle not only helps to further stillen tl1e sideboards, but forms a slanting surface, down which all such material assand, dirt, &c.,'will readily slide, thus assisting in thedumping of the box.

The operation is as follows: The boX being loaded with dirt or other material of a similar nature, the driver standing on the footboard 2 throws the operating-lever 14, say, to the left. disk 16 and revolve it with the rod b. Lever 11 will then move outward on its slotted end until the rear end of the slot will force plate 10 to revolve, thus revolving rod 4and' turning catches 5 out of vconnection with the latches '7. When at this point, the outer edge of the wing 2 having no support left it, the weight of the contents of the box will force it to swing downward or open, and that half of the load resting on that wing will be dumped.

'Ihe driver now desiring to dump the other halfoi` the load presses handle'15 against the lever 1l and throws-the lever in the opposite direction, which causes rod 6 to revolve and draw the catches 5 from the latches? on'that side of the' box-bottom, and that side will therefore dump on account o f the lever 12 Catch 15 will strike pin 18onk rolling the catches and rod in the 4proper drection; but as this 'is being done the winged pieces 9 9'on the rod 6 have assumed the position shown in Fig. 10, and the left-hand wing has turned, so asto press upward against the under side ofthe left wing of the box-bottom, and as the rod is continued to be turned this wing continues'to rise and forces the wing 2 of the bottom into place, and the revolving of the rod 6 also-throws' the catches 5 into en` gage ment with the latches 7 on that side, thus closing the leftwing of the bottom,'and by now throwing the operating-lever 14 in the opposite direction again just far enough to swing the wingedpiece 9 over and against the right bottom wing the right wing of bottom of the box will be closed without opening the left wing, and thus the box-bottom will be. closed, ready for being lled again. When the levers 11 and 12, withtheir slots 13, are' properly adjusted to the disks 16 and 17 and to the plates 10, these movements are readily carried out. The inverted-V piece 24 prevents dirt, &c., from filling the V-sliaped opening between the wings of the box-bot,- tom, while the truss-rod-23 keeps the rod 6 in position.

In Fig. 2 I have not shown the truss in order to more clearly show the other parts of the invention. A

I have shown the disks 16 and 17 as a means for operating the levers 11 and 12 and through them the rods 4 and their locking devices; but it will be at once perceived that other equivalent devices may be used in their place and stead, and I therefore claimv all such equivalents.

Having described m-y invention., claim is 1'. In' a dumping-wagon box, a bottom consistinglof a plurality of wings or doors; a centrally disposed revoluble rod under said wings or doors to which the wings or doors are hinged; winged members attached to said rod arranged to force the doors to swing upwardly; revoluble' rods disposed under the sideboards of the box; levers in connection with said last-named rods arranged to rotate them; -catches on said rods revoluble with them; a throwing-lever in connection with the levers on the rods arranged to operate them; latches in connection with the wings or doors forming the bottom of the box arranged to lock and unlock with thegcatches on the said rods, all arranged'and operating substantially what I as herein shown and described.-

'the' lower ends of which are formed and arranged 4as journal-boxes in which the revoluble rodsin the-grooves may turn; levers in connection with the last said rods arranged to rotate them catches on said rods revoluble with IOO them; a'throwing-lever inconuection with the rods arranged to operate them; latchesy arranged in connection with the wings or doors l forming the bottom of the b onx arranged to lock and unlock with the catches on the' rods as described.
